My 10 year old has hit a serious wall with regrouping for addition. She can do 2 digits plus 2 digits but add a 3 digit number and it is like she forgot all her math facts. We WERE doing so well in math and I am so frustrated.
It has been a week and I was wondering if anyone else has had these issues.
My current plan is to take some time off( maybe a week?) find other math activities and try again.
The try again is why I am here. HELP! Ideas? It seems such a simple concept to just keep bringing things to the next column. We do Singapore(2a). I have used number discs, the unit blocks , to try to Get the concept across. But once I add that one more digit it all flys out the window. I'm getting a little worried here. Is she OK?
Thanks in advance,

how about a paper covering the "extra" columns so she doesn't get overwhelmed when looking at it?

What if you have her do it the long way for awhile. add the thousands first, then hundreds, tens, ones
For ex.
1349
+832
_____
1000
1100
70
11
_____
2181
(sorry i don't know if when I hit send all those numbers will stay lined up. The 70 and 11 should be on the right under the tens and ones)
Have her do this until it is easy and then point out that instead of writing it out the long way we can carry. For ex. The 10 in 11 gets carried or the 1000 in 1100 gets carried. I would start with the four digit number. If you start addition with just one or two digits the kids tend to freak out when they see three or four.

Maybe you could try giving each column a color . . . ones could be red, tens could be blue, hundreds could be green, etc. Maybe she could keep the columns straight by their color.

Putting it in terms of money sometimes helps with place value.

Is it a hanging 3-digit? Like 122 plus 23, so the 1 in 122 is all by itself when stacked?
122
23
If so, maybe add a zero on the front of 23 to show that there are zero one hundreds and that lines up under the 1 in 122.
Or, is it more of an issue of carrying over the extras from the ones column to the ten's, and the ten's to the hundred's?
